TRIED AND TESTED
Screw piles were invented back in 1833. Initially made from cast iron, they were screwed down to depths of 20 feet by 30 men or more using capstan bars up to 40 feet long. Many of our Victorian pleasure piers are built on screw piles.
The uses of screw piles have been widely developed during the last 50 years, particularly in North America as one of the most practical systems for timber-framed housing and modular construction.
